    Abstract: It is disclosed a composite yarn structure (10) comprising: —a first element (15) comprising a coaxial flexible bi-component monofilament including a conductive component (20) and a thermoplastic component (30) exhibiting piezoelectric properties, —at least a second element (40) twisted around the first element (15), wherein the second element (40) has a lower elasticity with respect to the elasticity of the first element (15) such that, upon elongation of the yarn structure (10) in a first direction, the yarn structure (10) expands in a second direction, whereby the dimensions of the yarn are increased both in first and second directions to generate an additional force on said piezoelectric component of the first element.

    Abstract: It is disclosed an electromagnetic shield (1) and a related method for providing electromagnetic shielding wherein the shield comprises a shielding surface provided with a plurality of electrically conductive elements (2), said plurality of electrically conductive elements (2) being electrically connected to a switching assembly (3) configured to switch said electromagnetic shield (1) between an open configuration, wherein said electrically conductive elements (2) are electrically insulated from one another, and a shorted configuration wherein said electrically conductive elements (2) are electrically connected to each other at a common node (C). When the electrically conductive elements (2) of the electromagnetic shield (1) are switched between the open and shorted configurations, a change of the electromagnetic shielding effectiveness (EMSE) occurs. The electromagnetic shield (1) can be used for providing a shielding textile fabric (12), or an article that may comprise the electromagnetic shield (1) in form of a pocket preferably made with the shielding fabric (12).
